Life in Cold Blood

Animals

From a purely biological standpoint, cold-blooded amphibians and reptiles long have commanded the respect of scientists for their sheer resilience, if nothing else. These animals dominated the world for an estimated 200 million years, and today, more than 14,000 species of them still thrive. This BAFTA-winning series, written and hosted by David Attenborough and co-produced by the BBC and Animal Planet, examines these creatures in a new light, however, revealing them to be complex, social and passionate animals. Innovative techniques and equipment allow scientists to document behaviors that have been rarely seen, including a timber rattlesnake taking down its prey.
